Choice of Bike
This is for me the best bit getting to buy another bike!! ( I have over forty!!!) as you can see from the picture on the left its an old fashioned 50's Style Mans bike with Rod Brakes So for the Trad. look you need something like this. The Bike I use in the middle Picture is a Pashley Prospero. To be truthful if I was choosing again I would go for a ladies frame. Try getting your leg over that huge box on the back its a very balletic move! A step through frame is much kinder on the Human frame also they are often cheaper! The Pashley model is the Princess.
You don't have to be traditional, I have put my Kamishibai Box on the back of a recumbent trike The Anthro-Tech lots of advantages here it Cycles well lots of gears for the hills and is stable with the weight.
I have also put the Box on the back of the trike I use for my Punch and Judy show You just spin the show round from Punch to Kamishibai! See Top Right.
